Hi Harry,

 

You can cut a groove in the plywood with a router or a dado blade in a table saw.  Actually, the kerf from a single blade may be enough for the wires.

 

You can drill a hole in your bracket, which I assume are made of steel.  You shouldn’t have any problem with running wires through them, but make sure you run both bus wires through the same hole.  Otherwise you will make a little induction heater.  I remember seeing one Sn3 layout with welded steel framework and he didn’t seem to have any problems.  I have also seen references to people using metal strut like Unistrut to build layout framework.  I use aluminum shapes for framing on my lift-ups.   Buildings with steel studs have wires running through them, which seems to be most commercial buildings, at least around here.

 

Will there be a fascia on the front hiding the brackets, lighting, etc.?

Hi Everybody,

 

I have been a model railroader for a long time now and am currently building a new layout and I want to use DCC. I have a lot of questions. What I do know about DCC I have read in magazine articles or on-line groups. The biggest question I have right now is -- The layout I am building now is multi-level (three in all) and consist of 3/4" plywood supported by metal shelf brackets. Obviously I need to keep the wiring, etc from one deck so you dont see it on the lower level. I understand I shouldnt have a bus wire longer then 30'. I could run the bus wire under the plywood, and at each bracket drop it down, under and across. This would use up 5-6" of wire for each bracket. A 15' long section of the bench work has 11 brackets so I have used up over 5' of bus run. The best idea I have is to cut a groove in the plywood to allow the wire to run over the bracket and not lose any bus lenght. I did think about drilling hole, grommets, etc-- cutting a groove is much easier!. I would run the wire thru a short piece of rubber hose to prevent any contact between the bracket and the wire as well as wire supports in between each bracket. My question is this-- will running the bus wire thru metal brackets cause a problem of any kind? The brackets on the lower level extend out to the end of the plywood, the upper two level's brackets will be shorter to allow the lighing to be attached to the underside of the plywood. Thanks for any info and Im sure I have plenty of other questions.
